Description

Technical Field

[0001] The utility model relates to the technical field of open-pit mines, in particular to a support structure for an open-pit mine waste dump. Background Art

[0002] An open-pit mine strips the overlying soil and surrounding rock above and around the ore body, transports the waste rock to the waste dump, and directly extracts the ore from the exposed ore body. When the ore body is buried shallowly or there is an outcrop on the surface, open-pit mining is superior to underground mining. Due to the phenomenon of slope collapse during the excavation of open-pit mines, there are certain hazards. Therefore, it is necessary to support and protect the slope during the excavation process. Traditionally, methods such as using support steel plates in combination with slope support rods for reinforcement are mostly adopted. Since the widths of the support steel plates are the same, it is necessary to continuously measure the spacing of the support rods, and the deviation also needs to be corrected in real time during the construction of the support rods, resulting in a large construction difficulty. If the spacing between adjacent support rods is less than the width of the support steel plate, the steel plate needs to be cut or trimmed. Moreover, when one support steel plate is impacted, the adjacent support steel plates are likely to be vibrated, affecting their stability.

[0003] Therefore, it is necessary to provide a new support structure for an open-pit mine waste dump to solve the above technical problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a support structure for an open-pit mine waste dump.

[0005] The support structure for an open-pit mine waste dump provided by the utility model includes slope protection piles. A detachable protection steel plate is installed between two of the slope protection piles, and an elastic net bag for collecting rolling stones is hooked.

[0006] Wherein, a ground insertion rod is fixedly embedded at the bottom of the slope protection pile, and two symmetrically distributed U-shaped plates are fixedly welded on the column wall of the slope protection pile.

[0007] A side beam plate rotatably connected is further installed on the slope protection pile, and a plurality of hook rings are fixedly welded on both side plate walls of the side beam plate. A central connecting member for tensioning the slope protection piles is further installed on the side beam plate.

[0008] Preferably, a section of elastic corrugated steel sheet is arranged in the middle of the protection steel plate, and insertion parts for inserting the U-shaped plates are arranged at both ends of the protection steel plate.

[0009] Preferably, a threaded through hole is opened on the U-shaped plate, and a fastening screw rod connected by threading is inserted into the threaded through hole.

[0010] Preferably, hooks fixedly connected are sewn on the wire mesh on the side of the elastic net bag.

[0011] Preferably, the lower plate head of the side beam plate is rotatably connected to the pile wall of the slope protection pile near the bottom.

[0012] Preferably, the central link includes a rotating A plate and a rotating B plate, the rotating A plate and the rotating B plate are rotatably connected, the other end of the rotating A plate is rotatably connected to the plate wall of the side beam plate near the top, and the other end of the rotating B plate is rotatably connected to the pile wall of the slope protection pile near the top.

[0013] Preferably, the side beam plate is located on the slope protection piles between the two U-shaped plates.

[0014] Preferably, a hammer cap is fixedly installed on the top of the slope protection pile.

[0015] Compared with the related art, the open-pit mine dump support structure provided by the utility model has the following beneficial effects:

[0016] The utility model inserts the insertion parts at both ends of the protective steel plate into the corresponding U-shaped plates on the two slope protection piles respectively, and then tightens the fixing screws. The protective steel plate can effectively resist the soil pile on the slope edge of the open-pit mine. Since a section of elastic corrugated steel sheet is arranged in the middle of the protective steel plate, the elastic corrugated steel sheet can be stretched or compressed artificially, and then the width of the supporting plate surface formed by the protective steel plate can be flexibly adjusted. The protective steel plate cannot be installed between adjacent slope protection piles due to construction errors, which reduces the construction difficulty. The designed elastic corrugated steel sheet is an elastic structure, so the impact of the side protective steel plate on other adjacent protective steel plates after being subjected to lateral impact stress is reduced, thereby greatly improving the stability of the protective steel plate.

Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The specific implementation of the present utility model will be described in detail below in combination with specific embodiments.

[0024] Please refer to Figures 1 to 4 , a support structure for an open-pit mine waste dump provided by an embodiment of the present utility model, the support structure for the open-pit mine waste dump includes a slope protection pile 1, a protection steel plate 2 and an elastic net pocket 3.

[0025] In an embodiment of the present utility model, please refer to Figures 1 to 4 , a ground rod 12 is fixedly fitted at the bottom of the slope protection pile 1, and two symmetrically distributed U-shaped plates 13 are fixedly welded on the column wall of the slope protection pile 1. A ground rod 12 is fixedly fitted at the bottom of the slope protection pile 1, and two symmetrically distributed U-shaped plates 13 are fixedly welded on the column wall of the slope protection pile 1. A threaded through hole is opened on the U-shaped plate 13, and a fastening screw rod 14 connected by threads is inserted in the threaded through hole;

[0026] A detachable protection steel plate 2 is installed between the two slope protection piles 1. A section of elastic corrugated steel sheet 21 is arranged in the middle of the protection steel plate 2, and insertion parts 22 for inserting into the U-shaped plates 13 are arranged at both ends of the protection steel plate 2.

[0027] It should be noted that: a plurality of slope protection piles 1 are sequentially fitted to the edge of the open-pit mine slope, and an elastic corrugated steel sheet 21 is installed between two adjacent slope protection piles 1. Specifically, the insertion parts 22 at both ends of the protection steel plate 2 are respectively inserted into the corresponding U-shaped plates 13 on the two slope protection piles 1, and then the fastening screw rod 14 is tightened. The protection steel plate 2 can effectively abut against the soil pile on the edge of the open-pit mine slope;

[0028] Since a section of elastic corrugated steel sheet 21 is arranged in the middle of the protection steel plate 2, the elastic corrugated steel sheet 21 can be stretched or compressed manually, so as to flexibly adjust the width of the support plate surface formed by the protection steel plate 2. Due to construction errors of adjacent slope protection piles 1, the protection steel plate 2 cannot be installed between adjacent slope protection piles 1, reducing the construction difficulty. The designed elastic corrugated steel sheet 21 is an elastic structure, so the impact of the side protection steel plate 2 on other adjacent protection steel plates 2 after being subjected to transverse impact stress is reduced, greatly improving the stability of the protection steel plate 2;

[0029] Further, a hammering cap 11 is fixedly installed at the top of the slope protection pile 1 to prevent the impact hammer from cracking or damaging the top of the slope protection pile 1 when inserting the ground rod 12 at the bottom of the slope protection pile 1 into the formation.

[0030] In the embodiment of the present utility model, please refer to Figures 1 to 4 , a laterally beam plate 4 is rotatably connected to the slope protection pile 1. The laterally beam plate 4 is located on the slope protection pile 1 between two U-shaped plates 13, and a plurality of hook rings 41 are fixedly welded on both side plate walls of the laterally beam plate 4. A central coupling member 42 for tensioning the slope protection pile 1 is further installed on the laterally beam plate 4. Specifically, the lower plate head of the laterally beam plate 4 is rotatably connected to the pile wall of the slope protection pile 1 near the bottom, and the central coupling member 42 includes a rotating plate A 421 and a rotating plate B 422 which are rotatably connected. The other end of the rotating plate A 421 is rotatably connected to the plate wall of the laterally beam plate 4 near the top, and the other end of the rotating plate B 422 is rotatably connected to the pile wall of the slope protection pile 1 near the top;

[0031] An elastic net pocket 3 for collecting rolling stones is hooked between the two slope protection piles 1, and a fixedly connected hook 31 is sewn on the wire mesh on the side of the elastic net pocket 3.

[0032] It should be noted that: after the slope protection pile 1 is fixed, pull the laterally beam plate 4 outwards so that the rotating plate A 421 and the rotating plate B 422 rotate and form a "one" - shaped arrangement structure, so that the laterally beam plate 4 inclines towards the outside of the slope protection pile 1, and then hook the hook 31 on the side of the elastic net pocket 3 onto the hook ring 41. The elastic net pocket 3 can catch some stones rolling from the spoil bank, thereby reducing the hidden danger of stones hitting workers or bumping into mechanical equipment, and greatly improving the safety.

[0033] The working principle of the open - pit mine spoil bank support structure provided by the present utility model is as follows:

[0034] Insert a number of slope protection piles 1 into the open - pit mine slope edge in sequence, and install elastic corrugated steel sheets 21 between two adjacent slope protection piles 1. Specifically, insert the insertion parts 22 at both ends of the protection steel plate 2 into the corresponding U - shaped plates 13 on the two slope protection piles 1 respectively, and then tighten the fastening screw 14. The protection steel plate 2 can effectively abut against the spoil bank at the open - pit mine slope edge. Since an elastic corrugated steel sheet 21 is arranged in the middle of the protection steel plate 2, the elastic corrugated steel sheet 21 can be stretched or compressed manually, thereby flexibly adjusting the width of the support plate surface formed by the protection steel plate 2. Due to construction errors of adjacent slope protection piles 1, it is difficult to install the protection steel plate 2 between adjacent slope protection piles 1. The designed elastic corrugated steel sheet 21 is an elastic structure, so the impact of the lateral impact stress on other adjacent protection steel plates 2 after the side protection steel plate 2 is reduced, and the stability of the protection steel plate 2 is greatly improved;

[0035] After the slope protection pile 1 is fixed, the outer pulling side beam plate 4 is pulled to make the rotating A plate 421 and the rotating B plate 422 rotate and form a structure arranged in a row, so that the side beam plate 4 inclines outward from the slope protection pile 1, and then the hook 31 on the side of the elastic net 3 is hooked to the hook ring 41. The elastic net 3 can catch some stones rolling from the spoil heap, thus reducing the hidden danger of stones injuring workers or hitting mechanical equipment, and greatly improving the safety.

[0036] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
